Struct EventCtx 

pub struct EventCtx<'a> { /* private fields */ }

Borrowed view of an active lv_event_t. Valid only inside an event callback.

The lifetime parameter ties the context to the callback invocation — it cannot escape the handler.

Implementations

impl<'a> EventCtx<'a>

pub fn target(self) -> Obj

Widget that originally fired the event (innermost).

pub fn current_target(self) -> Obj

Widget the user is interacting with — may differ from target for bubbled events (this is the widget the callback was registered on).

pub fn code(self) -> lv_event_code_t

Numeric event code (LV_EVENT_*).

pub fn param_raw(self) -> *mut c_void

Event-specific parameter (opaque to safe callers — left raw because the type depends on the event code; rarely needed in practice).

Trait Implementations

impl<'a> Clone for EventCtx<'a>

fn clone(&self) -> EventCtx<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
